Specification of Letters Patent. Patg tqgd D fi 19pm Application filedDecember 13, 1919. Serial No. M l/5%.

To all whom it may concern.

Be it known that I, Tnnooonn F. ELLIs, a citizen of the United States,residing at Lena, in the county of Stephenson and State of Illinois,have invented certain new and useful Improvements in Silos, of which thefollowing is a specification.

This invention relates to new and useful improvements in silos.

no object of my invention is to greatly increase the strength at themeeting edges or joints of the respective blocks from which the silo isbuilt.

A further object of my invention is to provide for varying the relativeangularity of the blocks to increase or decrease the size or diameter ofthe silo.

With the foregoing and other objects in view that will appear as thenature of theinvention is better understood, the same consists in thenovel features of construction, combination and arrangement of partsillustrated in the drawings and more particularly pointed out in theappended claim.

' In the accompanying drawings, which are for illustrative purposes onlyand are there fore not drawn to scale Figure 1 is a side elevation of asilo constructed in accordance with my invention.

Fig. 2 is a horizontal section, taken on the plane indicated by thedotted lines 2-42 of Fig. 1.

Fig. 3 is a horizontal fragmentary sectional view, showing, on anenlarged scale, the joint between two adjacent blocks.

Fig. 4 is a detail perspective view of one of the blocks.

Referring to the drawings for a more particular description of theinvention, and in which drawings like parts are designated by likereference characters throughout the several views, the numeral 1represents a silo of the circular type, comprising the usual base orfoundation 2, upright wall 3, con sisting of two or more rows 4 and 5laid one upon the other with the joints between the blocks of theseveral rows disposed in vertical alinement, and the circularreinforcing wires or bands 6, 6 and 6 Each section of the silo is formedof a plurality of flat rectangular vertically disposed blocks 7, ofcement, concrete or other plastic material, and each block is formed inone side edge, throughout its entire length with a concave recess 7 andat its opposite edge with a corresponding tongue 8, the

blocks being arranged in place with the tongue of one block fitting inthe groove of an adjacent block.

In carrying out my invention, the respectlve blocks are provided attheir side edges with the longitudinal outwardly projecting reinforcingflanges 9. When the blocks are placed together, edge to edge, the outerfaces of the flanges are substantially radially disposed with relationto the silo structure and the spaces 10 between the outer faces of theadjacent flanges are filled with cement or other binding material 11.

()wing to the hinge or pivotal joint or connection between therespective blocks, the same may be arranged or adjusted at the desiredangularity and the diameter of the silo regulated accordingly. For thepurpose of illustration, the relative angularity between the blocks inFig. 3 is shown to be greater than that in Fig. 2.

It will be noted by reference to the drawings, that the blocks of thefoundation row are alternately of different lengths, the shorter blocksextending from the base or foundation 2, to points directly under oropposite the TGlDfOl'Cll'lg wires or bands 6 and the longer blocksextending from, the base to points, as a, intermediate the bands 6 and 6It will also be noted that the blocks of the succeeding rows are of thesame or equal length. By means of the above construction the blocks orstaves of the several rows may be placed directly over each other andare securely bound together or held against relative lateral movement.

From the foregoing description taken in connection with the drawings, itis thought that the construction, operation and advantages of myinvention will be readily understood without requiring a more extendedexplanation.

Various changes in. the form, proportions and minor details ofconstruction may be resorted to without departing from the principles orsacrificing any of the advantages of this invention as defined in theappended claim.

llaving described my invention, what I claim as new and desire to secureby Letters Patent, is

A silo comprising blocks rectangular in side elevation and arranged edgeto edge around the silo structure, each of the blocks being provided atone vertical edge with a groove and at its opposite vertical edge with atongue, the tongue of one block being received in the groove of theadjacent block, each block being provided at its outer side and at itsvertical edges with outstanding flanges which extend from end to end ofthe block, said flanges being provided with outer edge faces, the outeredge faces of the flanges of the adjacent blocks being angularlydisposed with relation to each other and substantially radially disposedwith re- 10 lation to the silo structure and a filling of cementmaterial closing the spaces between the outer edge faces of the flangesof the adjacent blocks.

In testimony whereof I aflix my si nature. 15
